Title: Improvements relating to the treatment of polyethylene surfaces
IPC: B29C48/08
Filed: 1953-11-18
Abstract: <PICT:0738474/IV (a)/1> Polyethylene surfaces, e.g. films, are treated with ozone at a temperature not below room temperature in the presence of an accelerator selected from the group consisting of halogens, hydrogen halides and nitrous oxide, to give improved adhesion to e.g. printing inks, metals, paper, nitrocellulose and polymers. The treatment is carried out preferably in ultra-violet light at a temperature between 150 DEG  and 325 DEG  C., and the ozone concentration in the treating atmosphere is preferably between 0.1 per cent and 5 per cent.  Copolymers of polyethylene with isobutylene, vinyl acetate, styrene and vinyl chloride may also be treated.  In an example, polyethylene is melt extruded, calendered, and passed continuously through the treatment chamber 2, in the air-gap between the orifice and quenching bath 4.  The walls of the chamber are formed in part of quartz glass through which ultra-violet light from mercury arc lamps 3 is transmitted. Specifications 557,544, 681,517, [Group III], and U.S.A. Specifications 2,430,860 are referred to.

Title: Control means for the release of safety appliances in vehicles more particularly passenger carrying automobiles
IPC: B60R21/01
Filed: 1972-07-07
Abstract: 1376650 Crash bags; control for vehicle safety appliances BAYERISCHE MOTOREN WERKE AG 7 July 1972 [16 July 1971] 32009/72 Headings B7B and B7H [Also in Division H1] A control means for the release of safety appliances such as inflatable bags in motor vehicles comprises a piston arranged for axial movement in a casing in which liquid pressure set up by throttling means activates a release means for the safety appliance. As shown the vehicle part 10<SP>1</SP> is displaced towards part 10 on impact and this movement is transmitted by piston 8 which forces liquid from space 9 via throttling holes 19, 191 into spaces 17, 17<SP>1</SP>, the bellows 20 permitting enlargement of space 17<SP>1</SP>. As a result of throttles 19, 19<SP>1</SP> a predetermined minimum back pressure overcomes the force of a spring 22 and the contact carrying member 15 is forced against release contacts 5 by the bulge formed in a membrane 14. Release contacts 5 are thus short circuited to initiate release of the safety mechanism (not shown). The control means may be incorporated in a bumper system comprising an hydraulic shock absorber.

Abstract: 1439368 Rocket propulsion units MESSERSCHMITT BOLKOW BLOHM GmbH 9 July 1973 [23 Aug 1972] 32578/73 Heading F1J The invention relates to a liquid propellant rocket unit which may operate either as a single propellant unit or as a bi-propellant unit, the propellants comprising hydrazine and a cryogenic oxidizer such as fluorine, oxygen di-fluoride or a mixture of oxygen and fluorine. The rocket unit shown comprises a combustion chamber 3 and propulsion nozzle 4, a hydrazine container 5a and a cryogenic oxidizer container 5b, the two containers being pressurized from a reservoir 11. For single-propellant operation hydrazine passes from container 5a to a reaction chamber 6 where it is decomposed catalytically, the decomposition gases then passing through a heat exchanger 7 which is not in operation, through line 10 to the rocket combustion chamber 3 before discharging through nozzle 4. For bi-propellant operation, hydrazine flows to the decomposition chamber 6 as before then through the heat exchanger 7 where the decomposition products are cooled, the cooled products then passing through line 9 where they are utilized to cool the rocket combustion chamber and nozzle before entering the combustion chamber 3. Cryogenic oxidizer such as fluorine passes from container 5b direct to the heat exchanger 7 where it is utilized to cool the hydrazine decomposition products, the fluorine being vaporized thereby, the fluorine vapour then passing through line 8 into the combustion chamber 3 where it reacts with the hydrazine decomposition products. The rocket vehicle comprises also two groups of control rockets 13a, 13b, 13c and 14a, 14b, 14c which are supplied with hydrazine decomposition products from the chamber 6 through lines 17, 18, the control rockets having suitable control valves. Alternatively the control rockets may receive hydrazine direct from the container 5a, there being decomposition catalysts associated with each control rocket.
